The 1965 National Football League Championship Game was the 33rd championship game for the National Football League (NFL), played on January 2, 1966, at Lambeau Field in Green Bay, Wisconsin. This was the first NFL championship game played in January, televised in color, and the last one played before the Super Bowl era.

The game matched the Eastern Conference champion Cleveland Browns (11–3), the defending NFL champions, and the Green Bay Packers (10–3–1) of the Western Conference. A week earlier, the Packers defeated the Baltimore Colts in a tiebreaker Western Conference playoff at County Stadium in Milwaukee, while the Browns were idle. The Packers were making their first appearance in the championship game in three years, since their consecutive wins in 1961 and 1962. Green Bay was relegated to the third place Playoff Bowl the previous two seasons, with a victory over the Browns and a loss to the St. Louis Cardinals.

The home field for the NFL title game alternated between the conferences; in odd-numbered seasons, the Western team was the host. Home field advantage was not implemented in the NFL playoffs until 1975.

With the 23–12 victory, the Packers won their ninth NFL title, sixth in the championship game era.
